Hillcrest Energy Technologies released a technical paper backing a shift from 400V AC to 800V DC power systems in AI data centers.
Modeling showed a single-stage ZVS AC-DC design at about 99% efficiency, up to 99.2%, versus 98% for a two-stage 800V approach.
The paper argued the single-stage layout can retain two galvanic isolation barriers while adding fault-management functions to address safety concerns.
It linked fewer conversion stages to lower component count, improved reliability, reduced cooling load versus conventional two-stage designs.
Hillcrest’s PCS1000 prototype was positioned as built on the same single-stage ZVS architecture evaluated in the analysis.
